Closed-case electronic calibration
This instrument features closed- case electronic calibration.
In other words, no internal electro- mechanical adjustment
is required. This instrument calculates correction factors
based on the input reference signals you feed into it during
the calibration process. The new correction factors are
stored in non- volatile EEPROM memory until the next
calibration (adjustment) is performed. The contents of the
non- volatile EEPROM memory will not change even when
the power is switched off.
Agilent Technologies’ calibration services
When your instrument is due for calibration, contact your
local Agilent Service Center to inquire about recalibration
services.
Calibration interval
A one- year calibration interval is adequate for most
applications. Accuracy specifications are warranted only if
calibration is performed at regular intervals. Accuracy
specifications are not warranted beyond the one- year
calibration interval. Agilent does not recommend extending
calibration intervals beyond 2 years for any application.
